了解海洋捕食者的觅食行为对于了解它们在生态系统中的作用及其对其他物种的影响至关重要（Boyd等人，2006年）。然而，对海洋捕食者觅食行为的研究往往在逻辑上是困难的，因为直接观察是不可能的。随着微型电子记录设备的发展，如时间深度记录器（TDRs），不同的活动和行为已被用来推断觅食行为（Le Boeuf et al. 1988，Boyd and Croxall 1992）。TDR的使用现在很普遍;然而，仅使用来自压力变化的潜水记录意味着通常很难确定动物是否在积极觅食或从事其他活动，如旅行或休息（Hindell等人，2010）。
Knowledge of the foraging behavior of marine predators is critical for understanding their role in the ecosystem and their impacts on other species (Boyd et al. 2006). However, studies on the foraging behavior of marine predators are often logistically difficult, since direct observations are rarely possible. With the development of miniaturized electronic recording devices, such as time–depth recorders (TDRs), different activities and behaviors have been used to infer foraging behavior (Le Boeuf et al. 1988, Boyd and Croxall 1992). Use of TDRs is now widespread; however, using just dive records derived from pressure changes means it is often difficult to determine whether animals are actively foraging or are engaged in other activities, such as traveling or resting (Hindell et al. 2010).
